Thanks for reaching out. As suggested by Brad, you should be able to install Illustrator 2022 on your computer if it has macOS Catalina or later. Do note that performance may be hampered when working on large/complex documents due to CPU/GPU/Memory constraints. You may learn more about the system requirements here: https://helpx.adobe.com/illustrator/system-requirements.html.
Kindly update this thread if you need further assistance. We'd be happy to help.
